[Xen-users] Compiling legacy LSI megaraid drivers (Linux 2.6.11) with xen 2.0.7?

[Navid Khalili <navid@xxxxxxxx>]

Hi all,

	I've been using Xen for a while and I am trying to install it onto a 
Dell Poweredge 2950.  The 2850 uses a PERC4/Di raid on motherboard, 
which requires the LSI Legacy SCSI Raid driver to be compiled into the 
2.6.11-xen0 kernel.  I've been recompiling the kernel by:
1. Go into the linux-2.6.11-xen0 directory.  Select the driver using 
"make ARCH=xen menuconfig" and then finding the appropriate menu option 
(CONFIG_MEGARAID_LEGACY=y)
2.  cd ..

3.  make kernels

At some point....I get the following warnings during compilation:

CC      drivers/scsi/megaraid.o
drivers/scsi/megaraid.c: In function `issue_scb':
drivers/scsi/megaraid.c:1132: warning: passing arg 2 of `writel' makes 
pointer from integer without a cast

pointer from integer without a cast
drivers/scsi/megaraid.c:1370: warning: passing arg 1 of `readl' makes 
pointer from integer without a cast


4.  go into dist/install/boot and copy the kernel to /boot

during boot of the new kernel, I never see the LSI megaraid driver 
load.  I assume that the above errors are symptoms of 
something...anyone have any ideas?  Has anyone had any problems similar 
to this?  I know I can get the RAID driver to cleanly compile and work 
under a non xen kernels....

Thanks in advance,

Navid Khalili
